Reorder vowel AM in Bangkok style.
Not that I like it, as it's now hard to spot wrong encoding,
but it's the easiest way to cover all cases with tone marks.

Subjoin glyphs with vertical stem should not be of mark class.
Previous commit caused AboveBase anchor to stop working.
Just reverting it is not enough, either. All the deep mark
compositions must be undone as well.

"BelowSideMark" is for SARA U, SARA UU.
"BelowRightMark" is for deep subjoined NA.
"BelowMark" is for deep vowel AO below, deep subjoined WA.
- Add uni1A60.deep and uni1A36.deep glyphs.
- Change "BelowRight" base anchors in subjoined forms to
"BelowRightMark", to let 'mkmk' apply separately from 'mark'.
- Add "BelowSideMark" base anchors to subjoined forms.
- Bump font version to 001.012.

Just the matching patterns; the existing prepending lookup already
applies.
- Add new rule to cover uni1A58.lai + RA + V in
"'ccmp RA reorder remove intermediate" GSUB.
- Add "RA-AngV remove intermediate lookup" subtable to
"RA remove intermediate" GSUB.
ANG-LAN + C + RA

Differenciate glyphs.
* fonts/Khottabun.sfd:

uni1A43.sub (spacing MEDIAL LA). It's not actually found in
manuscripts anyway.
- Make uni1A58 (MAI ANG-LAN) and uni1A59 (FINAL NGA) a bit
different. The two signs should be identical, but we need to
distinguish them to make incorrect code point usage easily
spotted.

2013-04-15 Theppitak Karoonboonyanan <[email protected]>
Harfbuzz support.

- Selectively set 'lana' script to GSUB rules, to get run by
Harfbuzz. Those with 'DFLT' only will be ignored.
- Handle NAA ligature with 'pstf' instead of 'ccmp', so that it
gets run after Indic preprocessing.
- Set glyph class for all glyphs, to make mark skipping in GSUB
rules possible. (GDEF is thus explicitly generated.)

class uni1A59 belongs to.
2011-08-11 Theppitak Karoonboonyanan <[email protected]>
* fonts/Khottabun.sfd:
- Add BelowRight base anchor to all subjoined glyphs.
- Support subjoined WA as reduced UA vowel form under another
subjoined consonant, e.g. "หลวง", by adding BelowMark mark
anchor to WA.
- Also move BelowMark base anchor for subjoined consonants to
center position, for proper alignment of WA below it. With this,
also move vowal OA BelowMark mark anchor to center accordingly.
(No move for U, UU vowels, center position is OK.)

other subjoined glyph.

condense glyphs for more proper width.

According to Wadhana's and Phraya Luang Mahasena's tutorials,
subjoined HIGH THA is only reshaped when combined with HIGH TA.
Otherwise, it's in scaled form.
Subjoined HIGH RATHA, however, has only one shape in Phraya Luang
Mahasena's. So, just conclude it accordingly for now, and use the
reshaped form for both uni1A2E.sub and uni1A5B (CONSONANT SIGN
HIGH RATHA OR LOW PA).
* fonts/Khottabun.sfd:
- Use reshaped form for subjoined HIGH RATHA.
- Add "uni1A32.uni1A33" ligature for "HIGH TA + subjoined HIGH THA".

* fonts/Khottabun.sfd:
- Re-create subjoined HIGH RATHA using scaled version.
According to Wadhana's Pali tutorial, CONSONANT SIGN HIGH RATHA
OR LOW PA (uni1A5B) is used for both HIGH RATHA and HIGH THA if
combined below RATA and HIGH TA, respectively, while the scaled
versions are used when combined below RANA and NA, respectively.
The subjoined LOW PA, however, has a slightly different shape.
So, it's not relevant to U+1A5B.
- Unreference uni1A5B as required.
